About Borage
Borage is an effortless annual with striking blue star-shaped flowers. The cucumber-flavored leaves and flowers are edible, and it is a powerful pollinator magnet that self-seeds freely year after year.
Direct sow after last frost — hates transplanting. Self-seeds so aggressively you plant it once and it returns every year. Great companion plant for tomatoes and strawberries. Harvest flowers daily to encourage more blooms.
Gardening in Idaho
Idaho has a semi-arid continental climate. Southern valleys are Zone 6-7 with hot dry summers; northern regions and mountains are colder. Excellent for root vegetables and cool crops.
